Automatic openacc loop partitioning
Fri Nov 13 14:22:00 GMT 2015
this patch applies automatic loop partitioning to loops that are marked 'auto'
and 'independent'. 'independent' is implicit inside a parallel region.
We were unnecessarily still emitting a sorry for the auto, seq and independent
clauses in omp lowering. The main event is in the target compiler, when we know
which partitioning axes are available. A simple DFS walk of the loops assigns
the innermost available partition to such loops.
